Compact Ultrasonic Sensors come in metal housings.

Press Release Summary:

Using time of flight measurement for position and level sensing applications, ultrasonic sensors come in stainless steel housing. Respective sensing ranges for M18 cube and M18 tubular designs are up to 1.2 and 2.2 m. Along with digital and analog outputs, features include pushbutton sensitivity adjustment and vibrating sound transducer. Detection occurs regardless of target color, transparency, or surface reflectivity and is not subject to interference from UV light or direct sunlight.

Original Press Release:

Compact Ultrasonic Sensors Now with Robust Metal Housings and Ultrasonic Technology

ifm’s new ultrasonic sensors are ideal for both position and level sensing applications. Ultrasonic sensors emit short bursts of high frequency sound waves. When the sound waves strike an object, an echo is reflected back to the ultrasonic sensor. The time it takes for the sound to travel to the object and back to the sensor (time of flight) is measured and converted into a distance for reliable detection in position and level applications.

Robust high-grade stainless steel housing for demanding applications

Sensing range up to 1.2 m in M18 cube design and 2.2 m in M18 tubular design

Vibrating sound transducer reduces the accumulation of dust and dirt deposits which can negatively impact sensor performance

Digital and analog outputs for object detection and level applications

Easy sensitivity adjustment via pushbutton

ifm’s compact ultrasonic sensors are ideal for detecting targets at long ranges (up to 2.2 meters), regardless of their color, transparency or surface reflectivity and are not subject to interference from UV light or direct sunlight.


Ideal for sensing clear objects and diffuse sensing of targets at long ranges, such as automobile windshields

Detects full or empty positions in stack height control applications

Senses position of the material loops the roller speed can be adjusted as required for non-contact web loop control

Detects roll diameters to determine when the material will run out; or for stamping applications where shiny metal surfaces can be challenging to detect with photoelectric sensors

Well suited for level applications with liquids and materials with uneven surfaces such as granules and powders
